BRAKE.

To all wlw/m t may concern.' i

Be it known that I, WILLIAM SaNDniRso-N,

a` citizen of the United States, and resident of Conneautville, in thecounty of Crawford and State of Pennsylvania, have invented a new and useful linproveinent in Brakes; and ll do hereby declare the following to be a full,

clear, and exact description thereof.

`and the like. lt comprises, generally stated,

Cil

a non-rotating' or stationary bearing, a rotating,` member, such as a shalt or wheel, abutnients, and wedgng means between an abutment and the bearing,-for example, a

u disc having,` a wedging connection. between it and the bearing, so that by the simple ro tation of the disc, friction may be created between the abutinents and the bearing and i the rotation of the shaft be retarded or stopped. lt also comprises other unprovements, as hereinafter particularly set 'torth and claimed.

in the acconnjianying drawing, lug. 1 is a vlougitudinal section of a" shaft hai-'intar the viuventuni applied thereto; Fig. fisla perspective View oi." a preferred term of the wedging disc; Fig. 3 is a perspective View oat the bearing showing the shaft in dotted lines and partly broken away; Fig. fl is a sectional View ot a siinplitied torni of the invention; 5v is a like view showing;- the invention as applied to a shaft passing` through a sleeve so as to avoid end thrust on 1the shaft; and 6 is another inodilication i et the invention.

My invention is applicable to any shaft or wheel bearings, and will be described, for eX- ainple, in connection with the shalt 1 mount ed in the stationary or non-rotating bearing 2, the sha'l't carrying the collars 3 and Il, riggiiflljvsecured thereto, and the wedging' disc 5 iittinp; between the bearing` Q and a collar 3, the wedgingf disc 5 having theoperating` lever or handle G. Between the wedging disc and the bearing is any suitable wedging means that illustrated being' the wedging laces 7 on the wedge disc 5, while the bearing has like wedging' faces 8 formed on the end tace thereofi 'llhis is one very simple torni ot the invention and is illustrated in Fig. Al. ltwill thus be seen that the shalt carries two collars rotating with it and held against disc, and by studs 111 secured on the Application filed November 6, 1918. Serial No. 261,388.

longitudinal movement and forming abutinents, and that until the bralre is applied the shaft is free to rotate with its collars l and 3 against the non-rotating bearing 2 and against the wedging disc 5. ln these operations it can be lubricated usual. To check the rotation ot the shalt or stop its ro tation, it is only necessary to swing the wedging or braking,` disc il so that its wedginp; 'faces contact with the wedginej faces of the non-rotating bearing, which forces .the

`face ofthe disc against the collar 3 and draws 'the collar Il against the opposite side or' the bearing, so creating; such strong wedge ing action that but little power is required to check or stop the rotation ol the rotating; shalt. rllhe wedge Ylaces o1: the braking dis or its*corresponding bearing can, oi' course, have the itorin oli' depressed wedge `faces ol' one or the other member and, as illustrated in Fig. il, during the tree or ordinary rotation oil the shaft, no greater space is occupied than the thickness ot thebralringr disc. Thus, by the simple vaddition oiI the wedgr` ing disc to the ordinary bearing', a powerful braking" means is provided. Y

ln the torni ot the invention illust ated in liip. 1, l may einliloy removable lrictioi'i or weilging; laces, tor example, as indicated in dotted lines the wedge face 10 on the bearing` 2,`whiich may have a tongue and groove connection 11 with said bearing?,` to resist rotation, and may be secured thereto by bolts 12,- the saine used on one or both ends ot tbe bearing?. The wedgiiip; tace may bc torrnezl as inclined depressions in the tace ot the tace ot the bearing'and seating in said depressions. lf all end thrust ol3 the brakingil; apparatuffi is to be avoided, ll may also einploj;y the con struction illustrated in Fiep. in which thev power driven shalt 17 carries what mir/:lit be termen a sleeve shaft 18 connected thereto by a key and lzey/-way 19 passing through the bearing' and the wedjggini dise Z3 and having the abntinents Q0 and Q1 at each end thereo'ln rl`he bearingr Q2 and the wedgingr disc 23 illustrated in said figure are eulargjed to `receive such sleere shalt which rotates within them. Thus, the braking; power niay be applied while relieving the inaiii driving` shattentirely troni endithrust.

ln Fia'. 6 is illustrated the application oft the invention i to rotating wheels, for ex ample7 the wheel 25, which can be rotated by any suitable means, belting or gearing, the wheel being' mounted on the non-rotating' shaft 26 supported in the bearing 2T and having abutments 28 and 2S). The .redn'inj; disc 30 is shown between the bearinfij and the lmtment 299 and by dra vfing; on the shaft, iiorces the abutment against the rotating wheel 25, and that wheel against the bearing 2,7 to ,give the brakingV action.

Another feature of the inrention which should be kept in mind is that the preferable direction or rotation of the shaft to which the brake is 'to be applied is in the direction opposite to the braking action oit the braking disc G. TWhere tl e brake is applied under such conditions.r while but little power is required to apply it, he natural rotation oi the shaiit prevents any possible juf-.niningij or grabbinf'; ot the brake, and the sliA/'htest reverse movement oi the braking' dise relieves the shatt 'from braking' strain.

rEhe invention 'is applicablek to many different uses, :tor example, in motor shafts, clutches, wheels, and in fact to any rotating' element mounted in bearings, providing a very simple7 cheap and compact brakingv means which tests hare shown to be er; tremely efficient. rl`he term shaft as used in the claims includes any such rotating member.

What I claim is l. In a brake, the combination of' a nonrotatingl bearing, a rotatable shaft extending therethrough, abutments secured to the said shaft on opposite sides oit the said bearing', one of said abutments being' adapted to rest flatagainst one end o said bearing7 and a wedging dise surrounding the said shaiit between the other abutments and the said bearing', the said disc having inclined wedging faces engaging;` with the said bearing.

2. In a brake, the combination of a non` rotating: bearing having a wedging iace. a rotatable shaft extending` 'through the said bearing, abutments secured to the said shaft on opposite sides of the said bearing', one oi said abutments beingi adapted to rest at against one end of said bearing. and wedging means between the other abutments and the said bearing.

3. ln a brake, the combination of a nonrot-atine' bearing;l haring; a removable end bearirigr tace, a shaft in the bearing, abutments on' the shaft, one ot said abutments beineauapted to rest fiat against one end of said bearing, and wedgz'ing' means mounted on the shaft between the other abutment and the bearingY and Contacting' with said removable end i'aee of the bea-ring.

4. In a brake, the combination of a nonrotating bearing having on one tace a re# movable wedging disc, a shaft in the bearing7 abutments on the shaft, and a wedging means mounted on the shaft between an abutment and said removable wedgring tace ot the bearing'.

5. in a brake, the combination of a nonretating bearing having' on one face a removable wedging` disc and on the other face a removable concentric disc. a shaft in the bearing, abutments on the sha-ift, one oi said abutments being); adapted to rest `(iat against one end oi' said bearing. and a wedding means mounted on the shaft between the other abutment and said remo y'able wedginn' face oi the bearing'.

6. ln a brake, the combination o'l' a nonrotatingg bearinehaving the wede'ingl iaee S at one end thereof'. a shaft in the bearing, abutments on said sha'it. and the brakingT disc 5 mounted on the shaft between an abutment and the wedge tace ot the bearing, s id weda'inn; disc having the wcdg'ingr ace 7 thereon. i

7. ln a brake, the combination'of a rotating' bearinff nona rotatable shaft therein. abutments on the shaft on opposite sides o'l" the said bea and a wedding' disc between the hearing; and an abutment. the wedge face et one member beineT sunken into that member for the reception of a nrojectinfr wedgljing face on the other membei'.

S. .ln a brake. the combination ot a nonro'liatinjf bearing'. a rotating' sha'tt (VXtendiner therethroue'ln abutments on said shaft. a wedgjjing' disc placed b tween the bearing and an abutment and having` nf'edggjing' faces disposed to come into MedlineY action in` the v opposite direction to the rotation ot the shaft.

9. ln a brake. the combimltion of an elongated tubular bearing. a shaft extending' rotatably through said bearing', a removable wedgringr disc secured to one end ot said bearing. a remoyaole conrentrie disc of larger diameter than said bearing;r and secured to the other end thereof. an abutment secured to said shaft adjacent to said concentric disk, a second abutment carried by said shaft and spaced from the other end oi said bearing"` a wedding; member surrounding' said sbart between .said last-named :ibutment. and the sa'd wedgz'iilgr disc arried by said bearing'. and a handle Ylor turning' said wedgring.Y member.

In testin'iony whereof. the ,said lfiLmAn Funimnson. hare hereunto set my hand.
